DECALCOMANIA AND DRYING- MACHINE FOR POTTERY.

Application filed July 18,

T 0 all whom it may concern:

Be it known that we, HERMANN BOGATY and JOSEPH L. BUoKLEY, citizens ofthe United States, residing, respectively, in Philadelphia,Pennsylvania,and Pittsburgh, Pennsylvania, have invented certain Imsprovements in Decalcomania and Drying Machines for Pottery, of which thefollowing is a specification.

Our invention relates to certain improvements in apparatus for applyingdecalcomanias to pottery. The decalcomania is placed on the potteryafter the pottery has been baked and the glaze placed upon it. This isusually done by hand. An adhesive is first applied to the pottery andallowed to stand until it becomes sticky. A decalcomania is then placedover this adhesive and water is applied to moisten the paper backing,which is removed and the surplus adhesive is washed off. The pottery isthen placed in racks, or boxes, and placed in a drier.

The object of our invention is to provide an apparatus for carrying outthe process so that decalcomanias may be placed more accurately andrapidly on the pottery and i the paper and surplus adhesive can be morethoroughly removed than heretofore, the pottery being dried as ittravels through the apparatus.

In the accompanying drawings:

Fig. '1 is a longitudinal sectional View of our improved apparatus forapplying decalcomanias to pottery;

Fig. 2 is a plan view; and

Fig. 3 is an end view at the front end 0 the machine.

1 is the casing. 2 is an endless belt conveyer having trays 3, pivotallymounted thereon to receive the pottery to which the decalcomania is tobe applied. These trays may be of any length and width desired and theconveyer chain may be of any type common to this class of machine. 4 isa comparatively small drier and 5 is a large drier. The conveyer passesaround guide wheels at 6 and 7 at each end of the apparatus. The upperrun of the conveyer passes around guide wheels 8, 9 and 10 in the drier4.

11 is a vertical partition, in the present instance, having an openingin which is a circulating fan 12 driven in any suitable manner. 13' areheating pipes, which may Specification of Letters Patent.

be placed at any convenient point to heat the air in circulation. Theconveyer then passes through a horizontal section b and then 'under aspray chamber 14 in which is a spray pipe 15 for spraying water to thepottery after a decalcomania has been applied. The conveyer passesthrough another horizontal section 0, around a guide wheel 16" and overa guide wheel 17, down under aguide wheel 18 to another wheel 19 andthen under a wheel 20. These several wheels are located in the largedrying chamber 5. The conveyer then passes from the drying chamber andthe pottery is cooled to such an extent that it can be removed at theend of d of the apparatus,

In the drying chamber 5 is a vertical partition 21. Connected to thispartition is a horizontal partition 22 extending under the conveyer agiven distance so as to confine the heated air in the drying compartment5. In the partition 21 is an opening for the circulating fan 23, drivenin any suitable manner.

24 are heating pipes, in the present instance, located back of thepartition 21, but these heating pipes may be placed at any convenientpoint and other means for heating the air in circulation may be usedwithout departing from. the essential features of the invention.

Pottery is placed on the trays at the forward end of the machine andadhesive is applied to the pottery while traveling in the space a. Thenthe trays pass into the small drier 4 so as to dry the adhesive to sucha consistency 'that a decalcomania may be ap.-

plied. Then as the trays, with the pottery 5, whereit is. completelydried. The pottery is discharged at the extreme end of the ap-'"'paratus and is removed from the trays, or, in some instances, the trays,with the pottery thereon, are removed from the conveyer. The potterythen passes through the necessary finishlng steps.

By the use of the above apparatus, it will be seen that a decalcomaniacan be placed accurately and rapidly on the pottery and the adhesive canbe properly dried before a decalcomania is applied so as to insure aperfect transfer of the decalcomania to the pottery. By immediatelyspraying water on the paper backing of the decalcomania, this backingcan be easily removed without distorting the pattern transferred. Oncontinuing the movement ot-the conveyer the pottery is dried without thenecessity of manually handling and stacking the'articles in racks, asheretofore.

W' e claim:

1. The combination in apparatus for applying decalcomanias to pottery,of a frame; an endless belt conveyer; a series of trays on the conveyerto carry the pottery; and two drying chambers spaced apart, one chamberbeing arranged to dry the adhesive, which is first applied to thepottery, the other chamber being arranged to dry the decalcomanias afterthey have. been secured to the pottery by the adhesive.

2. The combination in apparatus for applying decalcomanias to pottery,of a casing; an endless belt conveyer; a series of trays pivotallymounted on the conveyer,

said casing having a space over which the conveyer travels in ahorizontal path and at which point the adhesive is applied; a dryingchamber into which the conveyer carries the pottery so as to dry theadhesive to the proper consistency; a second hori-,

zontal space at which the decalcomanias are applied to the adhesive onthe pottery;

'means for moistening the paper backing of the decalcomanias; and adrying chamber spaced from the moistening means so as toallow time forthe removal of the paper and the excess adhesive, the drier being ofsuch a capacity that the pottery, with the decalcomanias thereon, isdried before removal from the end of the apparatus.

3. The combination of an endless belt conveyer; two drying chambers, thefirst drying chamber being of small capacity and the second dryingchamber'being of greater capac- HERMANN eoearr. Josnrn L. BUCKLEY.
